Product Description

EVT20T-CPT Black | 20.5-Inch to 12-Inch & 290mm Multi-Truss Conversion Plate — Matte Black Powder Coat

The EVT20T-CPT Black Multi-Truss Conversion Plate is a matte black powder-coated cross-system adapter that joins bolted plated truss to 290mm conical truss systems without introducing a visible finish break at the connection point. One face carries precision-drilled bolt-hole patterns for standard 20.5-inch and 12-inch end-plated (bolted) truss; the opposite face carries four removable conical half-couplers that pin directly into 290mm conical sections — merging two incompatible connection standards into one continuous structural line in a finish that absorbs light instead of reflecting it. Machined from a solid 12 mm thick slab of 6061-T6 aluminum alloy and coated in a factory-applied matte black powder coat, this 19.26-pound plate exists for environments where raw aluminum catches a camera lens, breaks a sightline, or glows under UV — broadcast studios where every overhead frame enters the background of a produced image, houses of worship where the congregation sees the ceiling grid every week, nightclubs where bare metal fluoresces under blacklight, and museum galleries where the architecture of the lighting structure is expected to vanish behind the work it illuminates.

Function & Application:

The EVT20T-CPT Black delivers the same cross-system adaptation as the standard silver plate with an added layer of finish discipline for visually controlled environments. On the bolted face, multi-pattern precision-drilled holes accept Grade 8 bolts that match both 20.5-inch and 12-inch plated truss end-plate configurations — one plate handles two bolted standards so you don’t stock separate adapters for each truss size. On the conical face, four half-conical couplers (spigots) seat into 290mm chord ends and lock with tapered pins and R-clips, giving you the same rapid tool-free connection used at every conical joint in the 290mm market. The couplers are removable and reinstallable — detach them for inspection or replacement and reattach without affecting the plate itself, keeping the adapter in service long after the original hardware has cycled through. A large central pass-through cutout provides clean cable routing for power, data, and signal lines at the transition point without pinching. All connection hardware ships included — 4× Grade 8 bolts, nuts, and washers for the plated side, plus conical couplers, tapered pins, and R-clips for the 290mm side — so the plate goes from packaging to connected structure with no separate parts order. Fabricated from EN AW-6061-T6 aluminum alloy under TÜV-certified manufacturing processes and finished in a matte black powder coat engineered to resist scratching, UV fade, and stage-chemical exposure under normal use conditions. The plate’s 20.5-inch square footprint and existing 5/8-inch bolt holes also make it a practical wall or ceiling mount base for 290mm conical truss — bolt the plate directly to a structural surface, pin 290mm sections into the conical couplers on the opposite face, and the result is a permanent dark-finish mounting point that requires no dedicated bracket and introduces no contrasting metal into the sightline.

Key Features

• Matte Black Powder Coat Finish: Factory-applied matte black powder coat over the full plate surface delivers a non-reflective, audience-ready appearance that integrates seamlessly with black truss runs, dark stage environments, and any production where exposed silver hardware would compromise the visual design.
• Dual Bolt-Pattern Interface: One face carries precision-machined hole patterns for both 20.5-inch and 12-inch plated truss bolt configurations — a single adapter that covers two bolted standards without requiring separate plates for each truss size.
• Removable Conical Half-Couplers: Four spigots on the opposite face connect directly to 290mm conical truss chord ends with standard tapered pins and R-clips. The couplers are removable and reinstallable — service or replace individual couplers without retiring the plate.
• 12 mm Solid Machined Plate: Cut from a single slab of 6061-T6 aluminum alloy — one continuous load path from the bolted face through to the conical face with no welds or laminations.
• Central Cable Pass-Through: An open cutout in the plate center provides unobstructed cable routing for power, data, and signal lines transitioning through the truss core at the conversion joint.
• Complete Hardware Kit Included: Arrives with 4× Grade 8 bolts, nuts, and washers for the plated connection and conical couplers, tapered pins, and R-clips for the 290mm side — full connection hardware for both faces, ready to install.
• Wall & Ceiling Mount Capable: The 20.5-inch square plate with pre-drilled 5/8-inch bolt holes doubles as a structural mounting base for 290mm conical truss — bolt the plate to a wall, ceiling, or structural beam and pin 290mm sections into the couplers on the opposite face for a permanent dark-finish installation without a dedicated mount bracket.
• TÜV-Certified Manufacturing: Manufactured under the same TÜV-certified production processes as the truss lines it connects — the conversion plate meets an equivalent quality standard to the structural sections on either side of the joint.

Who It’s For

• Broadcast Studio & Film Set Technical Directors — You’re building and maintaining overhead truss grids that live inside the frame of a produced image — news sets, talk show stages, sound stages, virtual production volumes — and every piece of visible hardware must read dark on camera. A raw aluminum plate between black truss sections catches light, creates a hot spot in wide shots, and pulls focus from the talent or the content. The EVT20T-CPT Black absorbs light instead of reflecting it, keeping the conversion point between your bolted house grid and conical extensions invisible from every camera angle, every focal length, and every lighting cue in the show file.
• House of Worship Production Teams — Your church or worship center has permanent truss infrastructure for lighting, projection, and audio that the congregation sees every single week. The building committee approved a clean visual, and a glinting silver adapter plate in the ceiling grid undoes that approval every time the house lights come up. The matte black conversion plate joins your existing bolted house truss to conical extensions or new 290mm sections and disappears into the ceiling line — maintaining the architectural aesthetic the design team specified while giving your production crew the cross-system flexibility to upgrade or reconfigure the grid without a visible hardware mismatch overhead.
• Nightclub & Themed Venue Owners — Your venue runs permanent truss installations under colored washes, UV blacklight, and moving fixtures where bare aluminum fluoresces, glows, and draws attention to hardware that’s supposed to be invisible. The matte black powder coat stays dark under every lighting condition — UV, saturated color, strobes, full blackout — so the conversion plate fades into the structure and the visual focus stays on the lighting design, not the rigging holding it up. Whether you’re connecting bolted house truss to conical extensions for a new fixture run or wall-mounting 290mm sections for a themed installation, the black finish keeps the hardware out of the guest experience.
• Museum & Gallery Installation Specialists — You’re mounting temporary or semi-permanent truss for gallery lighting, suspended displays, or interactive installations in spaces where the architecture of the support structure is expected to vanish behind the work it illuminates. The matte black plate merges with dark ceiling grids and black truss runs typical of gallery environments, and the wall-mount capability lets you bolt directly to structural surfaces through the 5/8-inch holes for overhead display support — pin 290mm conical sections into the couplers on the opposite face and you have a dark-finish mounting point that introduces no contrasting metal finish into the visitor’s sightline.
• Structural & Rigging Engineers — The EVT20T-CPT Black is a 12 mm solid 6061-T6 aluminum conversion plate with a factory-applied matte black powder coat, manufactured under TÜV-certified processes. It features multi-pattern bolt holes on one face and four removable conical half-couplers on the other, and can be specified as a structural wall or ceiling mount base for 290mm conical truss using the existing 5/8-inch bolt holes. The powder coat does not alter the plate’s structural properties or load-bearing capacity. Load calculations must be based on the weakest link in the connected system — do not rate the combined assembly above the capacity of the lowest-rated component on either side of the conversion point. All wall or ceiling mount applications require structural verification of the mounting surface and fastener selection by a licensed engineer. STEP and DWG files are available upon request.

Designed by Evolve Truss, the EVT20T-CPT Black is the cross-system adapter for environments where the structure has to work as hard visually as it does structurally — one matte black plate that joins two truss standards and disappears the moment the lights come on.

⚠️ Safety & Engineering Notice

❗ Critical Load Rating Information: Conversion plates affect overall beam deflection and load capacity of the connected truss lines. Always calculate loads based on the weakest link in the connected system. Do not suspend loads directly from the conversion plate itself. A licensed professional engineer must review all structures, particularly those mixing different truss types and sizes.

Important Guidelines for Safe Use:

• Inspect the plate, conical couplers, and bolt holes for deformation, cracking, or wear before every use. When removing and reinstalling conical couplers, verify that each coupler seats fully and securely before loading the connection.
• Ensure all bolts, nuts, and conical pins are properly secured; the plate must be fully connected on all designated points on both the bolted and conical faces.
• Handle with care during transport and assembly to prevent chipping or scratching the powder coat finish. Surface damage does not affect structural integrity but may impact appearance.
• The purchase of this product does not authorize specific installations; a licensed professional engineer shall review all structures that combine different truss types and sizes.

⚠️ Compatibility Warning for Mixed-Brand Builds

Crucial Steps for Safe Assembly:

• Verify Bolt Patterns: Bolt-hole spacing on plated truss varies between manufacturers. Measure the bolt pattern on your existing 20.5-inch or 12-inch plated truss and compare those dimensions against the EVT20T-CPT specifications before purchase.
• Check Chord Alignment: Ensure chord alignment is precise to prevent uneven loading across the bolted connections.
• Mixing incompatible plated truss with this conversion plate can compromise connection integrity and lead to structural failure.
